摘要： For monitoring a predetermined level of a liquid in a container an ultrasonic sensor is fitted on the outer surface of the container wall at a measurement point situated at the height of the level to be monitored, said sensor containing an ultrasonic transducer having a diaphragm in contact with the container wall. The components of the ultrasonic sensor including those of the ultrasonic transducer are grouped together in a sensor block which is releasably connected to an adapter secured to the container wall, this adapter being configured so that it can be secured in any way required to containers of differing shape and/or material.

摘要： A measuring device working with high frequency microwaves, especially frequencies above 70 GHz, comprises a microwave module for the production of microwave transmission signals and/or for the reception and processing of received microwave signals, and an antenna unit for the transmission of the microwave transmission signals and/or for the receipt of the received microwave signals. The measuring device has a cost effective, flexibly usable connection between the microwave module and the antenna unit suitable for the transmission of high frequency microwave signals, especially frequencies of 70 GHz and more. The microwave module and the antenna unit are connected to one another via a dielectric waveguide, via which a transmission of the microwave transmission signals from the microwave module to the antenna unit and/or a transmission of the received microwave signals from the antenna unit to the microwave module occurs.

摘要： The invention discloses a level measuring device which can be made up from components. It comprises a sonic or ultrasonic transducer which is arranged in a first housing and forms a self-contained functional unit; the electrical circuit arranged in a further separate housing forms a second functional unit. The functional units are so constructed that they can be assembled from the various components to a complete level measuring device in accordance with the required use conditions by arrangement of a steel plate above the sonic or ultrasonic transducer, or by potting with a commercially usual potting composition, or the selection of two different similar housings for receiving the sonic or ultrasonic transducer or the arrangement of selectively different but dimensionally identical sonic or ultrasonic transducers, and the selective mounting by means of a loose flange on a container, or by means of a suspension bracket in the interior thereof or above a drain.

摘要： Proposed is a fill-level indicator designed to indicate the level of the contents of a container or the storage level of a material at a storage place, the indicator having an ultrasonic transducer which is operated to act alternately as a pulse emitter and as a receiver. The ultrasonic transceiver (31,33,35) is surrounded by the fill-level indicator housing (21) to form an exactly cylindrical coaxial air gap (38) and has boundary surfaces which produce acoustic impedance jumps to reflect the acoustic energy emitted by the surface of the piezoelectric crystal (31).
